Connector: Both ends of each twisted pair are connected to the network card and hub (or switch) through installation connectors (commonly known as crystal connectors).
Coaxial cable: It is composed of a hollow cylindrical mesh copper conductor and a copper wire located on the central axis. The copper wire, the hollow cylindrical conductor and the outside world are separated by insulating materials. Compared with twisted pair, coaxial cable has strong anti-interference ability and good shielding performance, so it is often used for connections between devices or in bus-type network topology. According to the difference in diameter, it can be divided into two types: thin cable and thick cable.
Connectors: Connectors are installed at both ends of the thin cable and connected to the network card and hub (or switch) through a dedicated connector.
Optical fiber: Optical fiber is an optical fiber. It is a small, flexible medium that can transmit optical signals. An optical cable is composed of multiple optical fibers. Compared with twisted pairs and coaxial cables, optical cables adapt to the network's requirements for long-distance transmission of large-capacity information and play a very important role in computer networks.
Half-duplex: It means that although the network card can receive and send data, it can only do one action at a time and cannot send and receive at the same time.
Full-duplex: It means being able to receive and send signals at the same time. For example, a phone is a full-duplex transmission device. We can also send words to the other party while listening to the other party's speech. In theory, full-duplex transmission can improve network efficiency, but in fact it is only useful when it is coordinated with other related equipment. For example, twisted pair network cables must be used to enable full-duplex transmission, and the hub (B) connected in the middle must also be capable of full-duplex transmission. Finally, the network operating system used must also support full-duplex operation. Only in this way can the power of full-duplex transmission be truly unleashed.
rr/: This is an effective transmission method that has been used since its early days. The company's network card that was popular around the world used this method. The transmission efficiency of this transmission method is not easy to improve. Once a large amount of data is encountered, it will become a transmission bottleneck.
